[0002] Mould processing refers to the processing of forming and blank making tools, and also includes shearing moulds and die-cutting moulds. During the mould processing process, clamping and fixing the mould is particularly important to ensure processing accuracy and processing quality. In the prior art, since it is not convenient to replace the processing surface of the mould during the processing, the working efficiency of the device is reduced.

[0003] In the prior art, a Chinese patent with a publication number of CN212793977U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a clamping device for mold processing that is easy to adjust and control, comprising a working plate, a connection groove is provided on both the front and rear sides of the upper surface of the working plate, a clamping device is arranged inside the connection groove, and an auxiliary device is fixedly connected to the middle of the lower surface of the working plate. The clamping device for mold processing that is easy to adjust and control, by operating the operating handle to rotate and drive the clamping rod to move inward along the clamping tube, so that the clamping plate moves inward to clamp and fix the mold, thereby reducing the influence of the loosening of the mold on the processing quality during the processing, by controlling the push rod motor to move downward and drive the support block to move downward along the fixed frame to separate from the mold, and then pull out the fixed rod to operate the clamping tube to rotate along the rotating bearing, so that the clamping tube rotates to replace the processing surface of the mold, thereby shortening the time required to replace the processing surface and improving the working efficiency of the device.

[0004] Although the prior art can control the push rod motor to move downward to drive the support block to move downward along the fixed frame and separate from the mold, and then pull out the fixed rod to operate the clamping tube to rotate along the rotating bearing, so that the clamping tube rotates to replace the processing surface of the mold, thereby shortening the time required for replacing the processing surface and improving the working efficiency of the device, the radius of rotation of the mold that can be carried by its clamping device is fixed, and is limited by the size of the mold itself, resulting in only smaller molds being able to be flipped, thereby making the applicability of the device need to be improved.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The present invention is further described in detail below in conjunction with the embodiments:

[0029] Example 1

[0030] like Figure 1-6 As shown, the utility model provides a mold processing device which is easy to clamp, including a working plate 1, a clamping device 2 and a clamping support plate 3, both sides of the working plate 1 are overlapped with side expansion plates 4, and the bottom surface of the working plate 1 is provided with an expansion drive device 8 for driving the two side expansion plates 4 to move outward.

[0031] A support plate placement groove 7 is provided on the upper surface of the working plate 1, and a central support plate 6 is slidably connected to the inner wall of the support plate placement groove 7. A supporting hydraulic rod 10 for driving the central support plate 6 is fixedly connected to the bottom surface of the central support plate 6, and clamping side plates 15 are movably connected to both sides of the clamping support plate 3 through side plate sliding rods 16.

[0032] The expansion drive device 8 includes a positioning frame 11 fixed to the bottom of the working plate 1, and the inner wall of the positioning frame 11 is fixedly connected with a bidirectional hydraulic rod 12 for driving the movement of the side expansion plate 4. The output end of the bidirectional hydraulic rod 12 is fixedly connected to the bottom surface of the side expansion plate 4 through an auxiliary expansion frame 13.

[0033] The inner wall of the auxiliary expansion frame 13 is slidably connected with a guide slide bar 14, and the outer wall of the guide slide bar 14 is slidably connected with the inner wall of one side of the positioning frame 11. The guide slide bar 14 is used to auxiliary support and guide the auxiliary expansion frame 13, so that the outward movement and reset of the side expansion plate 4 are smoother and more stable, and then the clamping side plate 15 is used to support and limit the clamping support plate 3, so as to ensure the stability of the clamping work of the clamping device 2.

[0034] The outer wall supporting the hydraulic rod 10 is fixedly connected to the bottom surface of the working plate 1 through the supporting base frame 9 .

[0035] The bottom surface of the working plate 1 is fixedly connected with a supporting leg 5 for supporting the working plate 1 , and the bottom end of the supporting hydraulic rod 10 is fixedly connected to the bottom of the inner wall of the supporting leg 5 .

[0036] Example 2

[0037] like Figure 1-6 As shown, based on Example 1, the utility model provides a technical solution: preferably, sliding holes are opened on both sides of the clamping support plate 3, the inner wall of the sliding hole is slidably connected to the outer wall of the side panel sliding rod 16, and one end of the side panel sliding rod 16 is fixedly connected to one side of the clamping side panel 15.

[0038] A slide groove is provided on the upper surface of the side expansion plate 4 , the bottom surface of the clamping side plate 15 is slidably connected to the inner wall of the slide groove through a slider, and a universal wheel is fixedly connected to the bottom surface of the support leg 5 .

[0039] The working principle of the mold processing device which is easy to clamp is described in detail below.

[0040] like Figure 1-6 As shown, when the mold clamped by the clamping device 2 is large in size and needs to be flipped, the external power supply starts the bidirectional hydraulic rod 12, so that it pushes the two sets of auxiliary expansion frames 13 to drive the side expansion plates 4 on both sides to move to the two sides of the working plate 1. At this time, the support plate placement groove 7 will be relatively expanded. Then, the supporting hydraulic rod 10 is started to pull the central support plate 6 down on the inner wall of the support plate placement groove 7, thereby further expanding the depth of the support plate placement groove 7. Finally, the mold can be flipped by adjusting the clamping device 2 without any obstruction.

[0041] During the outward movement of the side expansion plate 4, the clamping side plate 15 will be driven to move away from the clamping support plate 3. At this time, the clamping side plate 15 will pull the side plate slide rod 16 to move in and out of the slide hole. The maximum outward movement distance of the side expansion plate 4 is less than the length of the side plate slide rod 16 in the slide hole, so that the support leg 5 always provides support for the clamping support plate 3, ensuring the stability of the clamping work of the clamping device 2.

[0042] When the bidirectional hydraulic rod 12 pushes the auxiliary expansion frame 13 to drive the side expansion plate 4 to move outward, the auxiliary expansion frame 13 slides outward on the inner wall of the guide slide bar 14, and the guide slide bar 14 is used to auxiliary support and guide the auxiliary expansion frame 13, so that the outward movement and reset of the side expansion plate 4 are smoother and more stable.

[0043] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
